4 Claims.

This invention relates to burners, and particularly to an improved burner using oil, the object being to provide a construction wherein crude oil or other low grade oil may be used with satisfactory results to secure a quick heating action.

Another object of the invention is to provide a heater utilizing oil and so formed as to produce a comparatively long flame capable of use with tubular water heaters and similar devices.

A further object, more specifically, is to provide an oil burner provided with a particular arrangement of air inlets and an oil-receiving chamber so associated with the other parts as to gasify the oil without spraying the same.

In the accompanying drawings,

Figure 1 is a vertical sectional view through a water heater provided with a burner embodying the invention.

Figure 2 is a vertical sectional view on an enlarged scale through one of the units shown in Figure 1.

Figure 3 is a cross sectional view through Figure 2 on line 33.

Figure 4 is a topplan view of the structure 1 shown in Figure 1, the same being on a reduced scale.

Referring to the accompanying drawings by numerals, 1 indicates a boiler and 2 a series of heating units coacting with the boiler and with the burner 3, which discloses an embodiment of the invention. As illustrated in the drawings, the burner 3 has been disclosed in connection with a storage or central boiler and with a number of heating units coacting with the boiler, the heating units being so formed as to provide a certain arrangement of tubular passageways into which the comparatively long flame from the boiler may enter and thus produce a desired heating action. In Figure 2 a heating unit with burner 3 is disclosed, the heating unit illustrating how there may be chambers having a construction for accommodating the body of water 9 which is provided by the various passageways 16, 34 and 35, which passageways accommodate the various flames from the combustion chamber 47 as the burner 3 functions. As shown particularly in Figure 2, the burner is provided with a;

base 38 having an integral standing central sleeve 39 and an outer sleeve 40 providing an annular chamber 41 for the reception of a certain level of oil. A disk 42 is carried by suitable members 43 and is preferably beveled on one face as is the upper end of sleeve 39, whereby a narrow annular passageway 44 is provided. Preferably, this passageway extends at a 45 angle and discharges air over the chamber 41 whereby the air will mix with the fumes rising from the fuel in chamber It will be understood that base 38, sleeves 39 and 40 and associated parts are very hot and consequently the oil fed into the chamber 41 by the pipe 44 will almost instantly vaporize and mix with the incoming air which is also heated by heat from the sleeve 39 and disk 42. Auxiliary air is fed in through the slits 45 and 46 whereby ample air is provided in the combustion chamber 4'? for the combustion of the fuel and for providing a very hot flame for heating the water in the fitting 5. The flame quite often extends upwardly an appreciable distance into the passageways 34 and 35 so that extremely hot water or extremely hot steam may be secured if desired, and an almost complete combustion of the fuel secured. The upright section 44' of pipe 44" is straight and slidably mounted in ears 48 and 49. A nut 50 acts as a support for the pipe 44" and also for the burner 3. A funnel-shaped member 51 is mounted on top of pipe 44 so as to receive the fuel from any suitable source, as for instance a supply pipe 52 having a discharge opening 53. Pipe 52 may receive its supply of fuel, as for instance crude oil, from any suitable source.

When it is desired to start the burner, nut 50 is unscrewed an appreciable distance to let the burner 3 be lowered a short distance, or a distance sufficient to permit a workman to discharge gasoline or other highly inflammable fuel into chamber 41. After this has been done, the burner is lit and the parts moved up into the position shown in Figure 2 and locked in this position by screwing nut 50 downwardly until it presses tightly against the ear 49. The gasoline is then ignited by any suitable ignition device so that the heat therefrom will heat the burner sufiiciently to gasify heavier oils when the gasoline has been consumed. Just before the gasoline or other highly inflammable fuel has been consumed, a supply of crude oil or other fuel is discharged into the funnel 5]. and said fuel will quickly pass into the chamber 41 where it begins to vaporize to continue the action of the burner.

By the construction of the burner 3 and the arrangement thereof with the heating unit, as illustrated in Figure 2, the passageways 34 and 35 accommodate the products of combustion including the flame from the burner so that the walls of these passageways are heated and the heat is transmitted to. the water in the various passageways 36 and 37. It will thus be seen that full value of the heater is secured in that the flame applies heat rather directly to a large volume of water in the units 2 and these various units may be arranged as shown in the drawings to supply heated water to the main reservoir or central boiler 1. It is, of course, understood that the burner could be used for other purposes and with different devices than that shown in the drawings, but Figure 2 particularly illustrates the desirable feature of the burner in that it accommodates and utilizes the comparatively long flame and products of combustion arising from the burner structure.

I claim:

1. A burner including a base having a hollow, centrally positioned, upstanding member with a chamfered upper surface, a disk-shaped valve member having a chamfered edge coacting with said ohamfered upper surface to provide a narrow air slit, said base having an annular shoulder and said valve having depending means resting on said shoulder for spacing the valve member from said chamfered face, a casing coacting with said base, said casing having a plurality of slits for the admission of air and means for sup plying oil to the upper surface of said base.

2. A burner including a casing having a pair of annular slots, notched brackets integrally associated with the casing on both sides of the respective slots for holding the parts together without interfering with the action of the slots, 2. base for closing the bottom of said casing, said base having a pair of spaced concentrically arranged tubular members, one of said tubular members fitting against the interior surface of said casing and the other tubular member being positioned substantially centrally of said base and forming an annular air inlet intermediate said slots, a valve member positioned at the upper end of said other tubular member for limiting the opening thereof, and means for directing oil to said casing.

3. A burner including a base having a hollow centrally positioned upstanding member with a chamfered uppersurface, a disk-shaped valve member having a chamfered edge coacting with said chamfered upper surface to provide a narrow slit through which air is adapted to enter the burner, a casing coacting with said base, said casing having a plurality of slits for the admission of air, and means for supplying oil to the upper surface of said base.

4. A burner of the character described com-'- prising a base having a pair of inner and outer concentrically positioned tubular upstanding webs, the inner concentric web being open atthe top and bottom for the admission of air while the outer tubular web merges into said base, a valve member coacting with the inner web and positioned over the upper end thereof, said valve member being spaced from the upper end of said inner web whereby an annular air orifice is provided, said base and web forming an annular combustion chamber, means coacting with the outer web forming a casing which forms an extension of said combustion chamber, said casing having a plurality of spaced annular inlet slits positioned to discharge air across the air entering through the passageway formed by said inner web, and means for directing fuel oil to the upper surface of said base.
